Input Capacitor

A 10µF ceramic capacitor is recommended for the

input. Select a capacitor that maintains its capacitance

over temperature and DC bias. Capacitors with X5R or

X7R temperature characteristics generally perform well.

Output Capacitor

A minimum of 10µF of capacitance is required at OUT

to ensure stability. Select a ceramic capacitor that

maintains its capacitance over temperature and DC

bias. Capacitors with X5R or X7R temperature charac-

teristics generally perform well.
